aio_fsync - asynchronous file synchronization
int aio_fsync(int op, struct aiocb *aiocbp);
Link with -lrt.
The aio_fsync() function does a sync on all outstanding asynchronous I/O operations associated with aiocbp->aio_fildes. (See aio(7) for a description of the aiocb structure.)
Note that this is a request only; it does not wait for I/O completion.
Apart from aio_fildes, the only field in the structure pointed to by aiocbp that is used by this call is the aio_sigevent field (a sigevent structure, described in sigevent(7)), which indicates the desired type of asynchronous notification at completion. All other fields are ignored.
On success (the sync request was successfully queued) this function returns 0. On error, -1 is returned, and errno is set to indicate the error.
The aio_fsync() function is available since glibc 2.1.
For an explanation of the terms used in this section, see attributes(7).
